Detailed Description
The principles and spirit of the present invention will be described below with reference to several exemplary embodiments shown in the drawings. It should be understood that these embodiments are merely described to enable those skilled in the art to better understand and to practice the invention and are not intended to limit the scope of the invention in any way.
Referring to fig. 1, an embodiment of the present invention provides a wind power generation device driven by a sprocket, which includes a rotating shaft 12, a fan blade mechanism, a main transmission shaft 11, a sprocket 5, a sprocket 6 and a rotating body 8. The rotating shaft 12 is positioned at the top of the whole device, and a plurality of fan blade mechanisms are horizontally connected in the radial direction of the rotating shaft. The lower part of the rotating shaft 12 is fixedly connected with a main transmission shaft 11, and the bottom of the main transmission shaft 11 is fixedly connected with a chain plate 5 which is horizontally arranged. The sprocket 5 is circumferentially driven around a plurality of sprockets 6. Each sprocket 6 is in driving engagement with the rotating body 8 for driving the rotating body 8 to rotate, and the rotating body 8 is further in driving connection with a rotor of the generator (not shown in the figure) for driving the rotor to rotate, thereby enabling the generator to generate electricity. A chassis 3 is arranged below the chain plate 5, and the chain plate 5 is in rolling fit with the chassis 3 through a steel ball 4. A support 1 is fixed below the chassis 3 to provide further support for the chain tray 5. The chain plate and the chain wheel are matched for transmission, compared with the speed reducer transmission in the prior art, the structure is simpler, multiple groups of chain wheels, rotating bodies and generators can be arranged around the chain plate, and the power generation efficiency is improved.
Further, an electromagnetic clutch (not shown in the figure) is connected between the sprocket 6 and the rotating body 8, when a plurality of groups of generators exist, when the wind power is insufficient, the control part of the electromagnetic clutch disconnects the corresponding sprocket 6 from the rotating body 8, so that the wind power can be ensured to sufficiently provide kinetic energy for the rest generators.
After the wind driven blade mechanism rotates, power is transmitted to the rotating body 8 and the generator at the bottom of the whole device through the rotating shaft 12, the main transmission shaft 11 and the chain plate 5, so that the generator is very convenient to maintain due to the fact that the generator is positioned at the bottom even if the generator fails.
The main transmission shaft 11 is formed by butt joint of a plurality of sections of sub-transmission shafts through connecting pieces. As shown in fig. 1, the main drive shaft 11 includes two sections of sub drive shafts 110, and a set of connection members 10 are provided at the lower end of the upper section of sub drive shaft and the upper end of the lower section of sub drive shaft. The connecting piece comprises a connecting sleeve 101 and a flange 102 fixed on the outer ring of the connecting sleeve 101. The connecting sleeve 101 may take the form of a cone sleeve or the like. When the two sections of the sub-transmission shafts 110 are in butt joint, the connecting sleeve 101 is firstly extended into the sub-transmission shafts 110 to realize the positioning of the relative positions of the connecting sleeve 101 and the sub-transmission shafts 110, for example, the connecting sleeve 101 and the sub-transmission shafts 110 can be welded together. The flange 102 is then abutted against a flange on the other terminal drive shaft, and secured by bolts or the like. Each sub-transmission shaft 110 can be prefabricated in a factory, and assembled and spliced according to the length of the main transmission shaft actually required after being transported to the site, so that the sub-transmission shaft has strong flexibility and is convenient for transportation in the early stage of construction.
The diameter of the rotating shaft 12 is larger than that of the main transmission shaft 11, and a supporting frame 7 is arranged below the rotating shaft 12. The inner side of the support frame 7 is kept at a distance from the main drive shaft 11. A circle of boss 71 is formed on the inner side of the support frame 7, and the lower part of the flange 102 at the joint of each sub-transmission shaft is matched with the boss 71 through a ball body 72. The arrangement of the ball bodies 72 allows the main drive shaft 11 to be supported at the connection node without affecting normal rotation. In this way, the weight of the entire main drive shaft 11 is transmitted to the support frame 7 in sections, ensuring reliable rotation. The bottom of the support frame 7 can be further supported by the support body 2.
In this embodiment, the fan blade mechanism includes a horizontally arranged sliding mechanism 13 and a fan blade 14 slidably engaged with the sliding mechanism 13. As shown in fig. 2, the slide mechanism 13 includes a slide mount 23 and first and second slide holders 15 and 16 that are slidably fitted with the slide mount 23, and the first and second slide holders 15 and 16 may be slidably connected by means of slide rails or the like constructed along the slide mount 23. The fan blade 14 is fixed to the first slide mount 15 and the second slide mount 16, and slides horizontally on the slide mount 23 together with the slide mount. When the wind force is small, the fan blade 14 can be slid to a position farther from the center of the specific rotating shaft 12, which is equivalent to the moment of the wind force acting on the fan blade, thereby improving the utilization rate of the wind energy and the power generation efficiency.
Specific examples are set forth herein to illustrate the invention in detail, and the description of the above examples is only for the purpose of aiding in understanding the core concept of the invention. It should be noted that any obvious modifications, equivalents, or other improvements to those skilled in the art without departing from the inventive concept are intended to be included in the scope of the present invention.
